With this parent-child relations are described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-main were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.

With this parent-child relation is described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-peripheral were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.

With this parent-child relation is described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-programmable were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.

With this parent-child relation is described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-system were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.

With this parent-child relation is described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-utmi were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.

With this parent-child relation is described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-sam9x60-pll were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.

Having parent_hw instead of parent names improves to clock registration speed and re-parenting. Extra time saved on registration is ~250us when running at 800MHz.
